Embodiment Construction

[0020] The implementation of the technical solution will be further described in detail below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0021] Such as figure 1 Shown, a kind of embodiment provided by the present invention, a kind of transparent clay, comprises deionized water, AVC polymer and carbon nanotube; The fraction ratio of described deionized water, AVC polymer and carbon nanotube is (180 ~200): (4~5): 1.

[0022] Further, the AVC polymer is ammonium acryloyldimethyltaurate / VP copolymer.

[0023] A preparation method of transparent clay, comprising the following steps:

[0024] Step 1: Weigh 180-200 parts of deionized water and put them into the sealed bucket 1;

[0025] Step 2: Weigh 4 to 5 parts of AVC polymer, and put it into the deionized water in step 1;

[0026] Step 3: Stir an...

Abstract

The invention discloses a transparent clay and a preparation method thereof, which comprises the following steps: taking an appropriate amount of deionized water and putting it in a sealed barrel, weighing an appropriate amount of AVC polymer, and putting it into a container filled with deionized water in step 1. In a sealed barrel; quickly stir and mix with a mixer, cover the sealed barrel lid after stirring evenly, and keep it in a cool place; weigh an appropriate amount of carbon nanotubes into the AVC colloid after standing in step 3, and stir slowly through a mixer After the carbon nanotubes are evenly distributed in the AVC colloid, use a vacuum pump to remove the air bubbles in the transparent clay, and then continue to place it in a cool place until the transparent clay is formed. The invention is simple and easy to operate. In addition, the AVC polymer has good rheology, high stability under the action of high shear force, moderate viscosity, and no stringing phenomenon, so it will not produce extreme when it is used as a transparent soil material. High cohesion.

Description

technical field [0001] The invention discloses a transparent clay and a preparation method thereof, and relates to the technical field of geotechnical engineering visualization model tests. Background technique [0002] To study soil deformation and seepage, the traditional method is to bury sensors inside the soil, but because the sensors are easily disturbed by the external environment, accurate measurement results cannot be obtained, and the displacement field change of the continuous deformation of the soil cannot be measured; or X-ray diffraction, CT scanning, nuclear magnetic resonance and other methods are used, but these methods are expensive and the test steps are cumbersome, so they cannot be widely used in geotechnical engineering tests. At present, transparent soil combined with image particle velocimetry technology can solve these problems very well, realize the visualization of soil internal deformation, simple operation and low cost, and can be widely used in ...
